the catch tax started with the first thing that was successful and they go to downtown manhattan and camped out in the square but what we love about this is if you could go back in time and talk to the guys who are inventing twitter and say to them in the future your creation, your platform you are building will be used to organize protests all-around world by hatch tags, they would have said what is a hash tag? they were not part of their platform. it was something users started to add. they didn't have any vision of political protests or even a vision of hash tags. that came from people using twitter in that way. when we create platforms that allow this creativity from ordinary people you see this great, rage ecosystem of discovery and invention that happen this. that is why i am optimistic about "future perfect: the case of progress in a networked age" because the government can create platforms and encourage ordinary people -- this is true in terms of local communities where the local government sets of the platform where anyone can report a pothole or some need in their neighbor
